expand a(4-,3,1)b(-2,4,-1)

expand

a (4 -, 3, 1) b (- 2, 4, - 1)

- 4 \cdot 2 ab, 4, - 4 \cdot 1 \cdot ab, 3, 1 \cdot 2, 4, ab, 3, 1 \cdot 1

Solution steps

a (4 -, 3, 1) b (- 2, 4, - 1)

= (4 - 3 \cdot 1,,) (- 2 \cdot 4,, - 1) ab

Expand

(4 -, 3, 1) (- 2, 4, - 1) : - 4 \cdot 2, 4, - 4 \cdot 1, 3, 1 \cdot 2, 4, +, 3, 1 \cdot 1

= ab (- 4 \cdot 2, 4, - 4 \cdot 1, 3, 1 \cdot 2, 4, +, 3, 1 \cdot 1)

Expand

ab (- 4 \cdot 2, 4, - 4 \cdot 1, 3, 1 \cdot 2, 4, +, 3, 1 \cdot 1) : - 4 \cdot 2 ab, 4, - 4 \cdot 1 \cdot ab, 3, 1 \cdot 2, 4, ab, 3, 1 \cdot 1

= - 4 \cdot 2 ab, 4, - 4 \cdot 1 \cdot ab, 3, 1 \cdot 2, 4, ab, 3, 1 \cdot 1

A (6, - 1) B (- 8, - 1)

2 \cdot (1 - pt (1.797, 87))

, a (x - 1) + b (x - 1) - (x - 1)

(\frac{15}{5})^{2}
